Main Circuits
Non-Fuse Breaker (NFB)
Used to protect the power lines:
overcurrent will shutoff the circuit.
Noise Filter (NF)
Prevents the external noise from the power
line, and reduces the effect of the noises gen-
erated by the servo motor.
Magnetic Contactor (MC)
Turns on/off the main power of the servo
motor.
Used together with a surge absorber.
Reactor (L)
Reduces the harmonic in the main
power.
Motor cable:
• Without a brake
• With a brake
Terminals P, B1 and B2
• Normally keep B1 and B2 shorted.
• If the capacity of the internal regen-
erative discharge resistor is not
enough, disconnect between B1 and
B2, and
connect an external regenerative dis-
charge resistor to P and B2 terminals.
